I just got my mefferts megaminx today. I was surprised to see the size of the puzzle.
Here's a few things I would like to know:
1)Is mefferts megaminx's size just like a Rubik's Cube's size?
2)What type of lube that they used to lube the mefferts megaminx, because I accidentally smell the lube(and I'm scared it might cause any side effects).

Thank you.

If you have one in your hands. Why can't you answer the first one yourself?

As for the second one, I doubt you'd suffer any side effects. The exposure hasn't been long, and I don't think you have absorbed many (dangerous) chemicals. If in doubt though, consult your doctor.
